Climate Change
What I find surprising is the sharp rise in public concern about the environment during the pre-Covid Trump administration, despite the administration’s anti-environmental rhetoric, aggressive deregulation and cost-cutting measures. Apparently, the administration’s top-down messaging was unable to override the inclination of Americans to care more about nature when bread-and-butters worries subside.
“News organizations increasingly use the terms “climate emergency” and “climate crisis” to convey the urgency of climate change; yet, little is known about how this terminology affects news audiences...[The results of our study] showed no effect of terminology on climate change engagement; however, “climate emergency” reduced perceived news credibility and newsworthiness compared to “climate change.” …No interactions with political ideology were found.” - Feldman & Hart (2021) Upping the ante? The effects of “emergency” and “crisis” framing in climate change news.
The following list is from “Adaptation Actions for Water Utilities” (Environmental Protection Agency. December 10, 2024). The EPA actually lists 49 adaptation actions and includes numerous examples and links. Read it while you can.
AI technologies can be used to analyze large amounts of data and identify patterns that aid in selecting superior plant varieties used in plant breeding to accelerate crop improvement and develop new varieties with higher yields and greater resilience to climate changes, such as more frequent and severe periods of drought.
AI Overviews are a wonderful tool but shouldn’t be considered the final word on a topic or query. They are, however, a good place to begin an exploration.
With that in mind, I’ll start subsequent Survive and Thrive posts with an AI Overview on the topic under consideration and then proceed to whatever more I’ve found out in my own explorations.
A year ago I posted Some Tips for Living in a Warmer World, which was rather long on dire predictions and short on tips. I hope to flesh out those tips in this series.
The last four posts focused on countries with the highest CO2 emissions as a percent of global CO2 emissions: total emissions per country, per capita emissions, changes in emissions since 2000, and the decoupling of emissions from economic growth. This post will look at global trends in CO2 emissions since 2000 and 2010.
It’s rather obvious from the above that CO2 emissions are no longer rising in sync with economic growth, ie, they have decoupled (for the most part).
Per the above chart, CO2 emissions have declined since 2000 in most of the high-income developed countries but are still climbing in several middle-income nations.
The Emissions Database for Global Atmospheric Research (EDGAR) is a joint project of the European Commission Joint Research Centre and the Netherlands Environmental Assessment Agency which estimates emissions of all greenhouse gases (GHGs), air pollutants and aerosols. The latest EDGAR report is a treasure trove of greenhouse gas emissions data…
This series of posts will focus on countries with the highest CO2 emissions: China, the U.S., India, Russia, Japan, Iran, Indonesia, Saudi Arabia, Germany, Canada, and South Korea. First, the percent of total global CO2 emissions for each country
Climate change and the environment were simply non-factors in this year’s election - no surprise, given that polls have repeatedly documented declining public concern about the environment. For example, in a recent Gallup poll “environmental quality” ranked 12th among issues that Americans worry about, after inflation, crime and violence, hunger and homelessness, the economy, healthcare affordability and availability, federal spending and the budget deficit, illegal immigration, drug use, the Social Security system, the possibility of terrorist attacks, and the availability and affordability of energy. That’s a lot of competition for scarce resources.
By 2023, US Fish and Wildlife and other US agencies had adopted a wildlife management framework called Resist-Accept-Direct, or RAD. The RAD framework allows natural resource managers the option to actively shape “change in ecosystem composition, structure, processes, or function toward preferred new conditions” (Schuurman et al, 2022). That option allows moving species outside their historic range, to benefit the receiving ecosystem, the migrating species, or both.
A sense of panic rarely leads to thoughtful planning. More often panic leads to bad policies, rushed implementation, poor outcomes, and political backlash. Better to tread carefully and self-correct as necessary.
So what does that mean for humans and the planet? Some predictions: unpredictable weather, extreme heatwaves, heat stressed cities, increased wildfires, severe droughts, water scarcity, increased frequency, intensity and/or amount of heavy rain and flooding, loss of species/mass extinctions, deforestation, lower crop yields, reduced food security, and widespread economic hardship. These problems will vary by region and local preparedness. Worst off will be countries that lack the resources or political will to build resilience and adapt to the coming onslaught of troubles…What to do?
On the left we have intensive farming, clearly not the way to go. On the right, “agroecological agriculture”, clearly on the side of virtue and biodiversity. Now here’s another example of intensive agriculture…
Ok, so global CO2 emissions continue to rise, except for a pandemic-induced dip in 2020. But look closely at the above chart and you’ll see definite signs of progress, especially since 2010. For one, CO2 emissions are increasing more slowly than global population and GDP per capita. Two, energy intensity - a measure of energy inefficiency - has been declining steadily for over 30 years. And, three, there’s an accelerating decline in “carbon intensity”, which means…
A recent study identified 101,583 square kilometers (km2) of mining operations across the globe, based on the latest satellite imagery (Maus, Giljum, da Silva et al, 2022). This figure includes open cuts, tailings dams, waste rock dumps, water ponds, processing plants, and other ground features related to the mining activities. To put that number in perspective, agricultural land covers over 47 million km2 worldwide. However, the amount of land devoted to mining increases every year - thanks in large part to the growing market for renewal energy and electric vehicles.
The biggest threat to biodiversity is loss of habitat. Agriculture is the main driver of habitat loss on the planet and a major source of greenhouse gas emissions. Climate change will reduce agricultural productivity unless crops become more resilient. GM crops require less land and are more resilient than conventional and organic crops.
President Clinton eventually signed the the Kyoto Protocol to the UN Framework Convention on Climate Change, but he never submitted it to the Senate for ratification. That’s because the Senate had already made it crystal clear that the vote would not go well: just two years before the Senate has passed a resolution 95-0 telling Mr. Clinton not to sign any treaty that committed the US to cut emissions without also requiring undeveloped countries to do so.
